Powders and Inorganic Materials. Y. Nonomura, in Cosmetic Science and Technology, 2017 14.2.1.3.2 Zinc Oxide. Zinc oxide, ZnO, is a hexagonal crystal–structured white powder that has a long history as a white pigment.However, the concealing property is smaller than titanium oxide due to a smaller refractive index of 2.03, and the optimal …
Owing to the similarities in the physicochemical and surface chemistry of the constituent minerals, separation of zinc oxide minerals from their gangues by flotation is an extremely complex process. It appears that selective leaching is a promising method for the beneficiation of this type of ore. However, with the high consumption of leaching ...
